In Low Voltage installations, when a Capacitor is switched ‘ON’, it results in resonant circuit damped to a greater degree. In addition to the rated current, over current of high amplitude (>180 In) and high frequencies (3~15 KHz) occur during transit period (1 to 2 ms). The resultant high in-rush current peaks, caused due to capacitor switching, depends upon following factors:

• Network inductances 
• Transformer power and short circuit voltage 
• Type of power factor correction: fixed or automatic 
• Harmonics presence in the system

The in-rush current of such high magnitudes is undesirable and it is likely to weld main poles of any standard contactor. Therefore, contactor for capacitor bank switching must be designed to withstand :

• Permanent current that can reach 1.5 time the nominal current of capacitor bank 
• Short but high peak current on pole closing.

Hence, selection of capacitor duty switching device requires careful product selection. It is always recommended to use dedicated Capacitor Duty Switching Contactor for switching Capacitor bank, which optimizes the switchgear cost & enhances the equipment life.

Features and Benefits:

• Excellent damping of In-rush Current 
• Reduced watt loss during ‘ON’ condition, saves energy 
• Capacitor Bank Switching in parallel without de-rating 
• Enhanced equipment life 
• Low maintenance & down -time 
• Power quality improvement
• Optimized solution cost

Salient Features:

• Modular design in 3 & 4 pole (63A ~3150A), suitable for utilization category AC-23A
• Easy maintenance as each pole can be replaced easily due to modular construction, saving cost of entire Switch in case of single pole being burnt or damaged.
• Available in open execution & in sheet steel enclosure. Complies with the latest requirements of IEC-60947-1&3 / 13947-1&3 standards.
• Unique self cleaning contact construction with special knife type (200A~1800A), double break switching contacts (63~160A & 1000~1800A) & single break (200A~800A). Positive opening operation, with quick make - break and effective arc splitting plates guarantee reliability and long electrical life of the Switch.
• Excellent tracking resistance of isolation material in switch frame prevents flashover between phases even in the most trying & difficult locations
• Adjustable telescopic shaft
• Compact construction
• Window for visual contact inspection
• Suitable for capacitor switching and as a Main switch
